This invention relates "to improvements in wringers and is directed to safety wringers so-called. The invention has for its. particular object the provision of a wringer for use in connection with a washing machine or the like which has incorporated therewith certain novel features of construction whereby an operator may easily and readily disconnect certain operating parts.

According to special features of the invention the wringer is so constructed and arranged that an operator may easily and readily take advantage of the safety features. In fact an operator may quite unconsciously and involuntarily disengage and move certain parts to an inoperableposition thereby safeguarding against personal injury.

Various novel features and advantages of the invention will be hereinafter more fully referred to in connection with the accompanying description of the preferred form of the invention, the same being illustrated in the accompanying drawings, wherein:

In describing the invention reference will be made to a frame, one form of which is shown in Fig. 5. lhis may have an upper cross member 2 and side supports 4. The.

wringer frame may take any usual form and that shown and to be described is merely for illustrative purposes. In describing the invention reference will be made to a wringer head H which may be supported by and operatively connected to a shaft of a washing machine or other device.

In Fig. 1, the head H includes a housing 6 which in some suitable manner is supported by a tube 8. This is adapted for connecting to a suitable support and a drive shaft 10 is journalled in the housing at its lower end for connecting to a suitable source of power. The shaft 10 may be continuously operated while the wringer may be connected thereto so that the rolls thereof may rotate in opposite directions or disengaged driving shaft 10, as will appear.-

A driving pinion 12 is carried by the upper end of the shaft :10. A barrel 14: is slidable and oscillatable in the housing 6 and is suitably fixed as by welding or by screws such as 18 to one of the members 1 4 of the wringer frame, so that the wringer frame and barrel may reciprocate and oscilhousing while its inner end 23 is rotatable in the barrel 14. A pair of gears 24 and 25 are fixed to the shaft 20 and as the shaft is moved in one direction or the other, either one of the gears is brou ht into mesh with the driving pinion 12 w ereby the shaft 10 nalled in .the supports 4 frame.

will drive the shaft 20 in one direction or the other.

A driving roll 30 has a shaft 32 thereof suitably. journalled in a support 4 at the left-hand side of the frame, while its righthand end extends through a part 34 within the barrel 14. Its extremity extends into and is fixed to the tubular shaft 20 by means of a pin or the like 36.

As the wringer frame is moved from left to right, it will be apparent that the barrel 16 is moved thereby and that this in turn moves the shaft 20 and gears back and forth for meshing with the pinion 12.

A pin 40 is carried by the barrel 14 and extends upwardly therefrom into a slot 42 in the upper side of the housing, as is shown clearly in Fig. 2.

The central part of the slot 42 is disposed angularly with respect to the axis of rotation of the-shaft 32 and has end portions 44 in offset parallelism which are disposed transversely to said axis. It will be readily obvious that if the frame of the wringer is tipped forward or back that the pin 40 will travel along the slot and move the barrel and consequently the gears 24 and 25 relative to the driving pinion 12 so that one of '3 the gears is brought into mesh withthe drivin pinion 12.

he parts are shown in Figs. 1 and 2 in a neutral position wherein the frame assumes a normal vertical position as shown in Fig. 4. In this position neither of the gears are in mesh with the driving pinion whereby the driving roll 30 is not connected for rotation A lock which may be in the form of a ball 50 is springpressed upwardly by a spring 52 in a bore 54 at the lower side of the housing and co-operates with an opening 56 in the lower side of the barrel so that the barrel and consequently the wringer frame are yieldingly held in the neutral position referred to.

An apron 60 is carried by the wringer frame beneath roll 30 and has side portions 62 and 64 for underlying clothes fed to the rolls. A driven 'roll 66 for contacting with the driving roll has a shaft 67 suitably jour In the operation of the wringer it will be assumed thattheoperator is to stand at the right-hand 'side'of the wringer as is shown in Fig. 4. In this case it may be desired to feed the clothes forwardly between the rolls and from the'operator .in the direction of the arrow F, asshown in Figs. 4 and 6. In this case the o' rator may move the frame to the left and t is may be doneby grasping the frame or 6. This movement ofthe frame will rotate the barrel 14 so that bymeans of the pin and,

of the wringer the apron 64 so as to move the. wringer frame to the position shown in Fig.

slot the frame and housing will be moved longitudinally of the housing and bring one of the driven gears into mesh with the driving pinion 12.

The shaft 10 may be rotated so that in this position the wringer rolls will be rotated in the direction of the arrows shown in Fig. 6.

With the parts in the position shown in Fig. 6, the clothes may be fed forwardly through the rolls. In case it is desired to instantly stop the rolls or to rotate the rolls in a reverse direction, the operator has but to press on the apron 64 or pull on the frame in order to swing the wringer to the neutral position shown in Fig. 4 orto the reverse position shown in Fig. 7.

' Frequently an operators hand or clothing becomes caught between the rolls inthe feeding of the clothes therethrough and it is therefore-to obviate this danger that this safety feature of this invention is directed. As stated, the operator need only hear on or against the apron 64 either with an arm or the body so as 'to cause the frame to swing to the upright neutral position or to the reverse position shown in Fig. 7. As the frame is thus swung the barrel is moved so as to disengage one of the gears or the one which is in mesh with the driving pinion, and thereby disconnect the driving roll from the shaft 10. With sufiicient pressure on the apron 64 the frame may be swung past its neutral position to engage the other are so constructed and arranged that the operator may involuntarily bring the safety feature into play.

.The modification of the invention shownin Figs. 8, 9 and 10 will now be described.

In this form'of the invention a housing 70 is provided which is similar to that already described and as in the former case a shaft 72 is rotatable therein which carries a driving pinion 74.

A- barrel 7 6 is associated with a sleeve 78- which'is reciprocable and oscillatable in the housing. The sleeve is fixed to an end port 79 of a wringer frame and a driving roll 80 has a shaft 82 rotatable in the barrel 76 with its outer end rotatable and reciprocable in .the housing. Gears 84 and 86 are fixed in spaced relation on the shaft 82 and are arranged to engage with the pinion 74.

sup-

The shaft 82, gears 84 and 86, parts 76, 78 and 79 are shiftable as a unit endwise of the housing. I A

A driven roll 90 has a shaft 91 suitably journalled between end frames such as 79 and is adapted to contact with the driving roll 80.

A collar 92 is arranged for oscillating movements on the housing70 and has radially disposed arms 94 extending therefrom. Bars 96 extend from the arms at either side of the frame and may have their left-hand ends joined together or suitably connected to a part. These bars are preferably disposed sov as to lie between the operator and the wringer whether the operator is at one side or the other of the wringer.

A pin 100 carried by the barrel 76 works in a longitudinal slot 102 of the housing and has its upper end in a slot 104 on the inner periphery of the collar 22. This slot 104 is angularly disposed as shown in Fig. 9 so that as the collar 92 is rotated the pin will be moved back and forth along the slot 102 and thereby move the barrel 7 (Sand gears 84 and 86 longitudinally of the housing and bring either one or the other of the gears 84 and 86 into mesh with the pinion 7 4.

The operator may grasp one of the rods 96 and this will depend of course upon which side of the wringer the operator is positioned. By moving oneof the bars 96 it is possible to rotate the collar 92 and thereby move one of the driven gears from engagement with the gear 74 and either bring the gears to an inoperative position or engage the other gear for rotating the rolls in an opposite position.

As in the former case the operator will involuntarily grasp a rod 96 and move the gears so as to either stop rotation of the rolls entirely or reverse them and in that way safeguard herself against injury.

The modification of the invention shown in Figures 11 12 and 13 will now be described in detail.

In this case a support 110 of a wringer frame similar to that already described is provided and has rotatable therein a shaft 112 of a lower driving roll 113 and a shaft 114 of an upper driven roll 115. A barrel 116 has a flange portion 118 fixed to the frame 110. Suitably spaced gears 118 and 120 are carried by the shaft 112 and are arranged to mesh with a driving pinion 122 associated with a housing 117 so that either one of the gears 118 and 120 may be rotated to thereby rotate shaft 112 in one direction or the other. The barrel 116 is' rotatable and reciprocable in the housing 117 which encloses the gears.

Lugs 130 extending forwardly from the flange 118 have rolls 132 which work on inclined faces of upper and lower cams 136 and 138 carried by'the housing. These cams forwardly between the bite of the roll 113 and 115. In order to rotate the rolls in the desired direction for wringing clothes the frame is tilted by the operator. As it is tilted it will be moved in one direction or the other longitudinally so as to engage either of the driven gears with the driving pinion. V

In case it is desired to stop rotation of the rolls or in the event the operator has. a hand caught between the rolls, all that is necessary to do is to tilt the wringer frame in an opposite direction. A partial tilting movement will of course bring it to a vertical neutral position wherethe gears are in inoperative relation. will tilt the frame to bring the other of the driven gears into engagement with the driving pinion and in that case the rolls will be rotated instantly in opposite directions.

In either of the embodiments of the invention shown the operator may stand at either side of the wringer: According to the direction of rotation of the driving shaft the gears may be engaged to rotate the rolls Additional movement are arranged so that as the frame is swung in the desired direction for receiving the clothes.

Regardless of which side of the wringer the operator is located it is possible to disengage the gears altogether or to cause a reverse rotation of the wringer rolls either by tilting the wringer frame in an opposite direction or by manipulating a rod 96- to the end that the operator is safeguarded against injury. The parts are so arranged that the safety feature is brought into play quite involuntarily by the operator. It is not necessary for the operator to reach for some inconveniently located part as is the case with prior art apparatus and which is quite difli- .cult in the event that the operator has a therewith, a frame member reciprocable rela- I tive thereto, driving and driven rolls associated with said frame member and a driven ber and driven gears associated with said driving roll shiftable by said frame member for alternately engaging said driving pinion accordingly as the frame member is moved in one direction or the other relative to said support.
